Note this will break OSX for now, so it should only be set for Linux (as it is done here). See the tracking issue conda-forge/clang-compiler-activation-feedstock#17 for that. Can we remove the explicit setting of CMAKE_CXX_STANDARD in CMake instead?

So this change is doing the "Right Thing"[tm] but maybe accidentally?

See the tracking issue conda-forge/clang-compiler-activation-feedstock#17 for that.

Ack.

Can we remove the explicit setting of CMAKE_CXX_STANDARD in CMake instead?

That is way above my pay grade (for this project). It depends on whether arrow supports any compiler where the default C++ version is < C++11. For example, GCC defaults to C++98 until GCC 6.x, and there is a similar story with Clang.

@pitrou do you have any thoughts on whether we can change the default for CMAKE_CXX_STANDARD?

Hmm. I'm not sure I understand the situation entirely, but for now Arrow C++ needs to compile on gcc 4.9 (and perhaps even gcc 4.8, for a subset of Arrow). This is because of the compiler requirements for R packages...

Also, unless I misunderstand @xhochy 's first message ("it should only be set for Linux (as it is done here)"), it seems there's no real problem here?

My message was mainly a heads-up that on OSX, you need to set CMAKE_CXX_STANDARD to 14. This is Linux here, so everything is fine here.

I'm not sure about the general removal of CMAKE_CXX_STANDARD as google-cloud-cpp does also set it: https://github.com/googleapis/google-cloud-cpp/blob/13ec1e946ae1baad6bcae952daf5910649dcfd0a/CMakeLists.txt#L31-L41 Possibly that combination could also be used here?

Well, we already have the following:

if(NOT DEFINED CMAKE_CXX_STANDARD)
  set(CMAKE_CXX_STANDARD 11)
endif()

The only difference AFAICT is that we don't error out if the user explicitly asked for something earlier than C++11, but that must be a really rare case.

@xhochy Can you remind me the reason of CMAKE_CXX_STANDARD=17 here? Also, perhaps explain it in a comment?
